RAILROAD TIE AND BED.

Specification of Letters Patent.

Patented July 8, .1 913.

Application filed October 19, 1912. Serial No. 726,630.

To all whom itmag concern:

.ie it known that I, Mann) IV. 'lnnrmga,

a citizen of the Republic of Brazil, South America, residing in the city of S210 Paulo, Brazil, South America, have invented a certain new and useful Improved Railroad Tie and Bed, of which the following is a specification.

This invention comprises an organization wherein there are railroad ties connected by intervening metal plates in the form of inverted arches. The metal plates are preterably longitudinally corrugated with respect to the track and the ties metal, and the two may be connected in a variety of ways as hereinafter suggested.

The organization has many advantages some of which are stated below.

Figure 1 is a perspective view showing a section of railroad track embodying this invention; Fig. 2, a detail section on the line 2, 9., of Fig. 1; Fig. 3, a side elevation; Fig. l, a view taken transversely of the track; Fig. 5, a plan view of what is shown in Fig. l; Fig. 6, a detail view taken at .right angles to the 'cross tie showing an in tervening plate seated in a side of the tie and secured bya bolt; Fig. 7, a side elevation in which the bed is not continuous; Fig. 8, a detail view indicating the shape of the ties in the organization of Fig. 7; and Fig. 9, a perspective view of a portion of a tie adapted to be used in the construction indicated in Fig. 1.

The metal cross ties may be of any cross section appropriate for the system of corn struction herein disclosed. In the drawings the ties 3 are in gene 'al cross section similar to structural I-iron. The upper and lower flanges, however, at each sidco't the central web are given a downward inclination, the two flanges, on each side being parallel or substantially so. At the points where the rails 4 are carried, the upper surface of the tie is formed with a horizontal face or platform 6, upon which the base flange of the rail rests and upon which it may be securedin any appropriate way.

Merely for purposes of illustration there have been shown bolts 7 passed, from beneath, upwardly through the tie, their lower ends being provided with heads 8 and their upper ends threaded to receive nuts 9 that overlie the base flange 01": the -ail and clamp it to its seat upon the tie.

The road bed between ties is formed by metal plates which are shown as provided with longitiulimil corrugations 11 and formed with a. curvature oi suitable radius. Their concave sides are turned uppermost and their edges seat in the sockets or slots formed by the flanges oi? the ties.

As indicated, in Fig. .l, the plates intervening between the ties may be composed of three separate sections riveted together as at 1.2, 12. This may be a desirable constriwtion on the score of economy since the center plate of the three may be o'l, lighter metal. I have also shown in Fig. 1, one oi? the intervening plates composml of two sections riveted together at l3. The remaining intervening plate illustrated in Fig. 1 an inlegral plate. These plates may be of sheet metal of appropriate thickness and ot' general longitudinal curvature of appropriate radius.

In Fig. 3, the horizontal dotted or broken line indicates the grade line of the road bed and the angular recesses formed between adjacent curved supporting plates 10 may be packed with earth, stone or other suitable material. The longitaulinal corrugations oi the plates 1.0 serve not only to strengthen and stil'len them but also to prevent lateral movement upon the foundation upon which they rest. Means should be provided particularly on. curves to prevent lateral move ment of the ties and the rails carried thereby relatively to the intervening plates 10. Any appropriate means may be employed, two being indicated in the drawings. Thus, Fig. (3 shows the use of headed bolts L1: to the threaded ends of which are applied nuts that may be locked or secured in any appropriate manner as also may be the nuts 9 indicated in Figs. ii and 5.

In Fig. 9, the upper flanges 3* of the ties are corrugated to con'lim'm to the corrugations of the intervening bed plates 10 so that the two will interlock.

In Figs. 7 and S, a modified construction is shown in that the road bed is not continuous. For that purpose the ties 15 may be of the cross section shown in Fig. S that is to say, there are flanges upon one side only of the central vertical web between which is received the edge of a corrugated plate 10. As appears from Fig. 7 there will be one such tie at the end of each plate and between that assemblage of parts and the next corresponding one there is an interval 17. This may be a construction of sufficient strength for small gage roads carrying light rolling stock. Such tics 15 have the upper flanges formed with horizontal flat seats 16 upon which the rails rest and to which they may be secured in the manner indicated in Figs. 4 and 5 or otherwise as may be desired, and the upper flange of the tie may be corrugated to interlock with the bed plate as in Fig. 9.

Of the many advantages incident to the construction described some may be mentioned as follows. The road bed composed of the ties and inverted arch plates permits perfect drainage; the plates nest conveniently for transportation and the work of road construction may proceed with rapid facility: the use of ballast is unnecessary and the construction affords an efficient cattle guard: compression strains are distributed and, without ballast, the united track, ties and intervening plates are held firmly against lateral strains or thrusts delivered through the rails. The construction is one economical with respect not only to construction and assemblage but as to cost of parts. When a composition of metal or a metal that is not subject to destructive corrosive action is employed the structure will have a prolonged life of indefinite length. Moreover, there is present such elasticity as will relieve the foundation and the rails and rolling stock of undue shocks and strains.

I claim:

1. A railroad construction comprising a pair of metal ties having seats for the rails and a means of securing the rails and between the ties a curved metal spacing piece forming an inverted arch between the ties.

2. A railroad construction comprising a pair of metal ties having seats for the rails and a means of securing the rails and be tween the ties a curved longitudinally corrugated metal spacing piece forming an inverted arch betweeen the ties.

3. A railroad construction comprising a pair of metal ties having seats for the rails and a means of securing the rails and between the ties a curved metal spacing piece forming an inverted arch between the ties interlocked therewith.

4. A railroad construction comprising a pair of metal ties having seats for the rails and a means of securing the rails and between the ties a curved metal spacing piece forming an inverted arch bet-ween the ties secured thereto against strains exerted transversely of the rails.

5. A railroad construction comprising metal ties having a central web and on each side parallel flanges and between the rails intervening metal plates seated at their edges between said parallel flanges.

6. A railroad construction comprising metal ties having a central web and on each side parallel flanges and'between the railsintervening curved metal plates seated at their edges between said parallel flanges.

7. A railroad construction 7 comprising metal ties having a central web and on each side parallel flanges and between the rails intervening longitudinally corrugated curved metal plates seated at their edges between said parallel flanges.

8. A railroad construction comprising ties each having a central body at either side of which there are laterally projecting flanges one of which flanges is formed transversely of its length with corrugations and intervening curved metal plates formed with longitudinal corrugations of appropriate dimensions to fit and interlock with the corrugations in the tie.

9. A railroad construction comprising a continuous road bed composed of metal cross ties and intervening curved metal plates placed as inverted arches between the ties.

10. A railroad construction comprising a continuous road bed composed of metal cross ties and intervening longitudinally corrugated curved metal plates placed as inverted arches between the ties.

11. A railroad construction comprising a plurality of metal ties and a plurality of intervening curved metal plates placed as inverted arches between the ties.

12. A pair of ties having side flanges combined with a curved metal plate placed as an inverted arch between the ties with its edges seated between said flanges.

13. A metal tie having a corrugated lat eral flange and a curved longitudinally corrugated bed plate interlocked with the tie.

In testimony whereof, I have hereunto subscribed my name.
